Coding method of ultra-thin glass

Abstract

The invention discloses a coding method of a piece of ultra-thin glass. The coding method comprises the following steps: (1) virtual coding is carried out on pieces of ultra-thin glass arranged successively at a conveying mechanism and a monitoring point for monitoring passing by states of the ultra-thin glass is arranged at one side of the conveying mechanism; (2), passing time t0 of each piece of ultra-thin glass passing by the monitoring point and a time interval t between time of leaving of the previous ultra-thin glass and time of arriving at the monitoring point by the next ultra-thin glass are obtained; (3), a transmission speed of a conveying belt is read, and equivalent time t1 of passing by the monitoring point by each piece of ultra-thin glass is obtained based on the widths and spaces of the ultra-thin glass and the transmission speed; (4) according to the time interval and the equivalent time, whether a piece of ultra-thin glass misses is evaluated and the number of missing ultra-thin glass is also assessed; and (5), the virtual coding information and information of the number of the missing glass are stored and code pasting is carried out on the stored information by a code printing mechanism. Therefore, accurate coding of ultra-thin glass of about 1 mm can be realized; the quality can be improved; and the cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of mirror preparation, in particular to an ultra-thin glass coding method. Background technique [0002] During production and processing, in order to achieve quality traceability and other purposes, it is generally necessary to code the product from the raw material side. The general method is to paste or print the code at the raw material supplier. However, when processing ultra-thin glass in the glass-plating banking industry, such as glass of about 1mm, it is impossible to paste the code before the silver-plated line, and it is also impossible to carry out laser coding, because it will affect the toughness of the glass, so it cannot be printed The silver-plated mirror produced is accurately associated with raw material information, inspection information, equipment information, etc., making it impossible to trace the quality and quickly locate the cause of quality problems.
